NEBULIZER
[0001] The present invention relates to a nebulizer for nebulizing a
fluid
according to the preamble of claim 1, 4, 17 or 33.
[0002] WO 2006/125577 A2 discloses a nebulizer which comprises, as
a reservoir for fluid which is to be atomized or nebulized, an insertable
rigid
container having an inner bag containing the fluid and a pressure generator
with a drive spring for delivering and atomizing the fluid. The container is
pre-installed in nebulizer in a delivery state. The pre-installed container is
held
by a transportation lock unmovable within the housing in the delivery state in
order to avoid any undesired opening of the container. Before being used for
the first time a lower housing part of the nebulizer is completely closed.
Thus,
the pre-installed container is opened by a delivery tube piercing a sealing
and
a septum to fluidically connect to the inner bag of the container. Further,
the
transportation lock is opened so that the container can move inside the
nebulizer back and forth.
[0003] By rotating the lower housing part the drive spring can be put
under tension and fluid can be sucked into a compression chamber of the
pressure generator. Simultaneously, the container is moved into the lower
housing part in a stroke movement within the nebulizer and when tensioned
for the first time the container may be pierced through its base by a piercing
element in the lower housing part to allow venting of the container. After
manual operation of a blocking element the drive spring is released and moves
the delivery tube into the pressure chamber so that the fluid is put under
pressure by the drive spring and is delivered or atomized through a nozzle
into
a mouthpiece as an aerosol, without the use of propellant gas.

100041 WO 2007/022898 A2 and US 2011/0011393 A1 disclose a
similar nebulizer. A container can be inserted into a housing of the
nebulizer.
The housing is closed by a lower housing part. The container is moving
axially forth and back during conveying of the fluid to be nebulized, and
during pressure generation and nebulization. A counter device can be arranged
in the lower housing part. The counter device locks the nebulizer against
further use if a predetermined number of operations has been reached or
exceeded. Then, the housing part may be replaced together with the counter
device and the container. The container may be connected inseparably with the
housing part. Further, the nebulizer comprises a device for permanently
locking the nebulizer when a certain number of containers have been used or
when a certain number of operations have been reached.
[0005] Object of the present invention is to provide a nebulizer
allowing
easy and/or improved handling.
[0006] The above object is achieved by a nebulizer according to claim
1, 4, 17 or 33. Preferred embodiments are subject of the subclaims.
[0007] A first aspect of the present invention is that the nebulizer
comprises an indicator member showing the number of containers that have
been used or can still be used, and showing in addition symbols indicating
container replacement. The numbers and symbols are shown alternately by the
indicator. This allows easy or improved handling or use of the nebulizer.
[0008] According to another aspect of the present invention, the
nebulizer comprises an indicator member showing the number of containers
that have been used or still can be used and/or the number of operations that
have been performed or still can be performed with this nebulizer, wherein the
CA 02834318 2013-10-24
WO 2012/162305
PCT/US2012/038969

indicator member is moved or rotated stepwise, i.e. indexed, or more generally
driven, by the force of a spring. This allows easy and/or improved handling or
use of the nebulizer. In particular, any additional manual force to drive the
indicator member or to use the nebulizer can be avoided. Instead, the spring
is
used preferably as an energy store to drive the indicator member and/or a lock
of the nebulizer.
[0009] According to a further aspect of the present invention, the
indicator member drives or controls a lock of the nebulizer such that the
nebulizer is locked against further use in a first locked state when the
container has to be replaced, wherein the first locked state is reset by
indexing
the indicator member and/or resetting the lock when the container has been
replaced. This allows easy and/or improved handling or construction of the
nebulizer as the indicator member controls the lock.
[0010] In general, the indicator member is preferably ring-like. This
allows a very simple and/or compact construction.
100111 Preferably, the indicator member works or shows said numbers
and/or symbols mechanically. This allows a very robust or simple construction
of the nebulizer.
[0012] According to another aspect of the present invention, the
nebulizer comprises a lock for locking the nebulizer against further use in a
first locked state when the container has to be replaced, wherein the locked
state is reset by resetting the lock when the container has been replaced, and
comprises further a control member for controlling or driving the lock,
wherein the control member is moved or rotated stepwise, with other words
indexed, or more generally driven, by the force of a spring. This allows easy
CA 02834318 2013-10-24
WO 2012/162305
PCT/US2012/038969
- 4 -
and/or improved handling or use of the nebulizer. In particular, any manual
force or the like can be avoided to drive the control member and to actuate
the
lock. Instead, the force of the spring is used as an energy source.
[0013] According to a further aspect of the present invention, the
lock
and/or first locked state is blocked in a second blocked state against
resetting
if a predetermined number of containers has been used. Thus, the lock can be
used not only for locking the nebulizer in the first locked state (which is
reversible when the container is replaced) but also for locking the nebulizer
in
the second locked state (final locked state or life span blocking), which
cannot
be reversed anymore. This double-function allows easy or improved handling
or use of the nebulizer as the construction of the nebulizer can be simplified
and/or made very secure.
100141 Preferably, the lock locks the nebulizer in the locked state
against conveying of fluid into a pressure generator and/or against tensioning
of a drive spring of the nebulizer. This allows easy and/or improved handling
of the nebulizer, in particular as it allows intuitive handling of the
nebulizer.
[0015] Preferably, the control member or lock locks the nebulizer or
its
housing part against opening or container replacement before the first locked
state has been reached and/or in the second locked state. Thus, early opening
of the nebulizer and early container replacement can be avoided. Further,
opening of the nebulizer and container replacement can be prevented in the
irreversible final locked state, i.e. in the second locked state. This
facilitates
intuitive handling. Further, it can be prevented that the nebulizer is opened
before the respective container has been (sufficiently) used or has been
emptied. Thus, potential soiling of inner parts of the nebulizer can be
minimized and/or a defined handling can be secured.

[0016] According to another aspect of the present invention, the
nebulizer comprises a securing device associated to a replaceable container of
the nebulizer, wherein the securing device prevents that the associated
container can be connected or used with the nebulizer once more after it has
already been used with the nebulizer, wherein the securing device comprises
locking portions, in particular arms, which force apart and/or move radially
when the container is or has been connected to or with nebulizer for the first
time and/or after the used container has been detached from the nebulizer such
that the use container cannot be connected or used the nebulizer once more.
This allows easy and/or improved handling of the nebulizer. In particular, it
allows a very secure and simple construction.
100171 According to another aspect of the present invention, the
nebulizer comprises a housing part which holds the container inseparably and
which can be attached to the nebulizer for connecting the container to the
nebulizer, wherein the housing part comprises a coding such that the housing
part can be attached to the nebulizer and the container can be connected to
the
nebulizer only if the coding matches with a coding formed at the nebulizer or
an inner part of the nebulizer. Preferably, the coding is formed at the
housing
part by one or more coding elements that can be attached to the housing part
by clipsing and/or inserting. Preferably, the coding is formed at the
nebulizer
or inner part by a retaining part provided with one or more coding portions,
wherein the retaining part is connected to the nebulizer or inner part by
clipsing and/or inserting. This allows a very simple realization and
adaptation
of the coding so that only certain housing parts and containers can be used
with a nebulizer.

100181 The above aspects of the present invention and the further
aspect
described below can be realized independently from each other, and in any
combination.

a modified embodiment.
[0036] In the Figures, the same reference numerals are used for
identical or similar parts, resulting preferably in corresponding or
comparable
properties and advantages, even if the associated description is not repeated.
[0037] Figs. 1 and 2 show a known nebulizer 1 for atomizing a fluid 2,
particularly a highly effective pharmaceutical composition, medicament or the
like, diagrammatically shown in a non-tensioned state (Fig. 1) and in a
tensioned state (Fig. 2). The nebulizer 1 is constructed in particular as a
portable inhaler and preferably operates only mechanical and/or without
propellant gas.
[0038] When the fluid 2, preferably a liquid, more particularly a
pharmaceutical composition, is nebulized, an aerosol 14 (Fig. 1) is formed,
which can be breathed in or inhaled by a user. Usually the inhaling is done at
least once a day, more particularly several times a day, preferably at set
intervals, depending on the complain or illness from which a patient is
suffering.
[0039] The nebulizer 1 is provided with or comprises an insertable or
replaceable container 3 containing the fluid 2. The container 3 thus forms a
reservoir for the fluid 2, which is to be nebulized. Preferably, the container
3
contains multiple doses of fluid 2 or active substance in particular
sufficient to
provide up to 200 dosage units or doses, for example, i.e. to allow up to 200
sprays or applications. A typical container 3, as disclosed in
WO 96/06011 Al, holds e.g. a volume of about 2 to 20 ml.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969

100401 It has to be noted that the dose can vary, in particular
depending
on the fluid 2 or medicament. The nebulizer 1 can be adapted respectively.
100411 Further, the number of doses contained in the container 3
and/or
the total volume of the fluid 2 contained in the container 3 can vary
depending
on the fluid 2 or respective medicament and/or depending on the container 3
and/or depending on the necessary medication or the like.
100421 Preferably, the container 3 can be replaced or exchanged,
wherein the number of containers 3, which can be used with the same
nebulizer 1, is preferably restricted , e.g. to a total number of four or five
containers 3.
[0043] The container 3 is preferably substantially cylindrical or
cartridge-shaped and once the nebulizer 1 has been opened the container 3 can
be inserted therein preferably from below and changed if desired. It is
preferably of rigid construction, the fluid 2 in particular being held in a
collapsible bag 4 in the container 3.
[0044] The nebulizer 1 comprises preferably a pressure generator 5
for
conveying and nebulizing the fluid 2, particularly in a preset and optionally
in
an adjustable dosage amount. The nebulizer or pressure generator 5 comprises
preferably a holder 6 for releasably holding the container 3, a drive spring 7
associated to the holder 6, only partly shown, and/or a blocking element 8
preferably in form of or with a button for preferably manual actuation or
depressing, which blocking element 8 can catch and block the holder 6 and
can be manually operated to release the holder 6 allowing drive spring 7 to
expand. The nebulizer 1 or pressure generator 5 comprises preferably further a
conveying element, such as a conveying tube 9, a non-return valve 10, a
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 10 -
pressure chamber 11 and/or an nozzle 12 for nebulizing the fluid 2 into a
mouthpiece 13. The completely inserted container 3 is fixed or held in the
nebulizer 1 via the holder 6 such that the conveying tube 9 penetrates into
the
container 3. The holder 6 is preferably constructed so that the container 3
can
be exchanged.
[0045] When the drive spring 7 is axially tensioned in the tensioning
process the holder 6 with the container 3 and the conveying tube 9 are moved
downwards in the drawings and fluid 2 is sucked out of the container 3 into
the pressure chamber 11 of the pressure generator 5 through the non-return
valve 10. In this state, the holder 6 is caught by the blocking element 8 so
that
the drive spring 7 is kept compressed. Then, the nebulizer 1 is in the so-
called
activated or tensioned state.
[0046] During the subsequent relaxation in the nebulization process
after actuation or pressing of the blocking element 8 the fluid 2 in the
pressure
chamber 11 is put under pressure as the conveying tube 9 with its now closed
non-return valve 10 is moved back in the pressure chamber 11, here in the
drawings upwards, by the relaxation or force of the drive spring 7 and now
acts as a pressing ram or piston. This pressure forces the fluid 2 through the
nozzle 12, whereupon it is nebulized into the aerosol 14, as shown in Fig. 1.
[0047] Generally, the nebulizer 1 operates with a spring pressure of 5
to
200 MPa, preferably 10 to 100 MPa on the fluid 2, and/or with a volume of
fluid 2 delivered per stroke of 10 to 50 IA, preferably 10 to 20 Ill, most
preferably about 15 IA. The fluid 2 is converted into or nebulized as aerosol
14, the droplets of which have an aerodynamic diameter of up to 20 jim,
preferably 3 to 10 1.1m. Preferably, the generated jet spray has an angle of
20
to 160 , preferably 80 to 100 . These values also apply to the nebulizer 1
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969

according to the teaching of the present invention as particularly preferred
values.
[0048] A user or patient (not shown) can inhale the aerosol 14,
preferably while an air supply can be sucked into the mouthpiece 13 through
at least one optional air supply opening 15.
[0049] Preferably, the nebulizer 1 or drive spring 7 can be manually
activated or tensioned, in particular by actuation of an actuation member.
[0050] The nebulizer 1 comprises preferably an upper housing part 16
and an inner part 17 which is rotatable relative thereto (Fig. 2) having an
upper
part 17a and a lower part 17b (Fig. 1), while an in particular manually
operable (lower) housing part 18 is releasable fixed, particularly fitted or
held
onto the inner part 17, preferably by means of a retaining element 19.
Preferably, the housing parts 16 and 18 form a housing of the nebulizer 1. In
order to insert and/or replace the container 3 the housing can be opened
and/or
the housing part 18 can be detached from the nebulizer 1 or its housing.
[0051] The actuation member, preferably the housing part 18, can be
actuated, here rotated relative to the upper housing part 16, carrying with it
or
driving the inner part 17. As a result the drive spring 7 is tensioned in the
axial
direction by means of a gear or transmission (not shown) formed between the
inner part 17, in particular its upper part 17a, and the holder 6 and acting
on
the holder 6. During tensioning the container 3 is moved axially downwards
until the container 3 assumes an end position as shown in Fig. 2. In this
activated or tensioned state the drive spring 7 is under tension and can be
caught or held by the blocking member 8. During the nebulizing process the
container 3 is moved back into its original position (non-tensioned position
or
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 12 -
state shown in Fig. 1) by the drive spring 7. Thus the container 3 executes a
lifting or stroke movement during the tensioning process and during the
nebulizing process.
[0052] The housing part 18 preferably forms a cap-like lower housing
part and fits around or over a lower free end portion of the container 3. As
the
drive spring 7 is tensioned the container 3 moves with its end portion
(further)
into the housing part 18 or towards the end face thereof, while an aeration
means, such as an axially acting spring 20 arranged in the housing part 18,
comes in contact with base 21 of the container 3 and pierces the container 3
or
a base seal thereon with a piercing element 22 when the container 3 makes
contact with it for the first time, to allow air in or aeration.
[0053] The nebulizer 1 comprises preferably a counter device 23, which
counts the actuations of the nebulizer 1, preferably by detecting its
tensioning
or the rotation of the inner part 17 relative to the upper part 16 of the
housing.
Preferably, the counter device 23 or an associated lock locks the (further)
actuation or use of the nebulizer 1, e.g. blocks further rotation of the
housing
part 18 / inner part 17 and, thus, tensioning of the nebulizer 1 or its drive
spring 7 and/or blocks actuation of the blocking element 8, when a certain
number of actuations or operations or discharged doses has been reached or
exceeded.
[0054] A preferred construction and mode of operation of the inhaler
or
nebulizer 1 will now be described in more detail with reference to Fig. 3 to
5,
but emphasizing only essential differences from the nebulizer 1 according to
Figs. 1 and 2. The remarks relating to Figs. 1 and 2 thus apply preferably
accordingly or in a similar manner, while any desired combinations of features

WO 2012/162305 PCT/US2012/038969
- 13 -
of the nebulizer 1 according to Figs. 1 and 2 and the nebulizer 1 described
below are possible.
100551 Preferably, the container 3 is pre-installed. This can be
realized
in particular as shown in WO 2006/125577 A2 or as described in the
following.
100561 Fig. 3 shows the nebulizer 1 in a delivery state with
preferably
pre-installed container 3, which is still closed. In this state, the housing
of the
nebulizer 1 is not completely closed, in particular the housing part 18 is not
completely pushed on the inner part 17. Fig. 4 and 5 show the nebulizer 1 in
an activated state with the housing completely closed and with the container 3
opened. In Fig. 4, the nebulizer 1 or drive spring 7 is tensioned, i.e. the
container 3 is in its lower position. Fig. 5 shows the nebulizer 1 in a non-
tensioned state, e.g. after dispensing or nebulizing of one dose of the fluid
2;
the container 3 is in its upper position.
100571 The container 3 comprises a fluid outlet 24 for outputting the
fluid 2 to be dispensed. In particular, the fluid outlet 24 allows a fluidic
connection between the container 3 or its bag 4 on one hand and the nebulizer
1, its pressure generator 5 or the conveying element on the other hand.
100581 The fluid outlet 24 has an inner closure 25 that is preferably
formed by a septum, a membrane, a plastic seal or the like and/or is provided
inside the container 3. Optionally, a second or outer closure 26 can be
provided such that successive opening is possible by means of one common
element, in particular the conveying element or conveying tube 9 or the like,
and/or by piercing.

[0059) Preferably, the first or inner closure 25 is formed or
supported
by a closure part 27 extending from the outlet or head end of the container 3
into the container 3 or bag 4. The second or outer closure 26 is preferably
located adjacent to the head or axial end of the container 3 and/or held or
connected to a flange 28, which can be formed by the closure part 27 or any
other suitable part. However, other constructional solutions are possible.
100601 In the delivery state according to Fig. 3, the container 3 has
been
pre-installed, i.e. inserted into the nebulizer 1. However, the container 3 or
its
fluid outlet 24 is not yet opened. In particular, the second closure 26 is
already
opened, but not the first closure 25. This is achieved in particular in that
the
housing of the nebulizer 1 is closed only partly, i.e. not completely, in the
delivery state.
100611 In particular, the container 3 is attached to or held by or
secured
in the housing part 18, in particular by a transportation lock 29, which is
preferably arranged within or at the housing part 18. The transportation lock
29 holds the container 3 preferably temporarily, in particular before
attaching
the housing part 18 to the nebulizer 1 and/or in the delivery state. In
particular,
the transportation lock 29 holds the container 3 fixed during the fluidic
connection of container 3 and/or during the mechanic connection of container
3, here with holder 6. Preferably, the transportation lock 29 holds the
container
3 fixed during opening, in particular piercing, the container 3.
100621 In the delivery state, in which the nebulizer 1 can be shipped
or
delivered to the user or is still packed, the nebulizer 1 or the housing part
18 is
preferably secured, in particular by means of a securing member 30, e.g. a
banderole, such that the container 3 and/or housing part 18 are held
sufficiently spaced from the nebulizer 1 or upper housing part 16 and/or
CA 02834318 2013-10-24

prevented from being completely closed or completely inserted or pushed on
the conveying element or tube 9, the housing or inner housing part 17 or the
like and/or such that (complete) opening of the container 3, namely of the
first
closure 25, is prevented.
[0063] Once the security member 30 has been removed a user (not
shown) can push the housing part 18 fully on in the axial direction and
thereby
open the container 3, i.e. first closure 25, by inserting the conveying
element
or conveying tube 9. Figs. 4 and 5 show this activated state with the housing
part 18 pushed fully on and/or the container 3 open (fluidically connected to
the nebulizer 1 or its pressure generator 5 or the conveying element or tube
9).
[0064] Fig. 4 shows the nebulizer 1 or container 3 in the activated
state,
the container 3, i.e. first closure 25, is open, i.e. the container 3 or its
fluid 2 is
fluidically connected to the nebulizer 1 or its pressure generator 5, and the
housing part 18 has been pushed fully on in the axial direction. In order to
bring the holder 6 into (complete) engagement with the container 3 at the head
end and then be able to move the container 3 back and/or forth for the
suction/tensioning and pressing strokes, it may be necessary to tension the
nebulizer 1 or it drive spring 7 for the first time. During this tensioning
process the holder 6 is moved together with the conveying tube 9 axially
towards or into the housing part 18, thus bringing the holder 6 into
(complete)
engagement with the container 3 and preferably also moving or pressing the
container 3 against the piercing element 22 in the region of the base of the
housing part 18 and thereby piercing or opening a venting hole 31 in the
container base 21. Fig. 4 shows the nebulizer 1 in this tensioned and
activated
state. The holder 6 is engaged with the container 3 and the conveying tube 9
has been fully inserted into the container 3.

container 3 are in the upper position. The holder 6 is still engaged with the
container 3 and remains engaged during the further uses of the nebulizer 1.
Further, the container 3 is still open and fluidically connected, i.e. the
nebulizer 1 remains activated.

the first closure 25, in the delivery state of the nebulizer 1, and/or to
prevent
(axial) movement of the container 3 relative to the associated housing part 18
before complete closing of the nebulizer 1, preferably the transportation lock
29 is provided. By frictional, forcible or interlocking engagement, for
example, the transportation lock 29 prevents the container 3 from undesirably
moving axially.
100671 Preferably, the opening of the transportation lock 29 occurs
automatically when closing the nebulizer 1 or its housing completely, i.e.
when snapping or pushing on the housing part 18 completely towards the
upper housing part 16. During this (preferably linear, axial or telescopic)
closing movement, the transportation lock 29 is opened and the container 3
released in axial direction preferably during or after piercing or opening the
container 3 and/or preferably during only a last part of the movement and/or
just little before the final completely closed position is reached or just
when
the final completely closed position is reached.
10068] During the closing movement the transportation lock 29 is
preferably opened by the direct or indirect interaction with or actuation by
the
housing of the nebulizer 1, the inner part 17 or its lower part 17b or the
like.
Preferably, the container 3 and/or first closure 25 are opened as well as the

transportation lock 29 by means of a common actuation and/or component,
here the closing movement of the nebulizer 1 or its housing or bottom part 18.
100691 Figs. 4 and 5 show the transportation lock 29 in the open
position, i.e. wherein the container 3 is free to move axially.
100701 In the following, a preferred embodiment of the nebulizer 1
according to the present invention will be described in more detail with
reference to the further Figures, wherein only essential differences from the
nebulizer 1 described above or shown in Figs. 1 to 5 will be emphasized or
described. Thus, the remarks relating to Figs. 1 to 5 apply preferably
accordingly or in a similar manner, while any desired combinations of features
are possible.
100711 Fig. 6 shows the nebulizer 1 in a perspective side view with
not
yet mounted, i.e. separated (lower) housing part 18 (partly cut open for
illustration purposes) with associated container 3. The container 3 has not
been inserted or pre-installed in the nebulizer 1 yet. With other words, the
nebulizer 1 has not been assembled yet or is not in the preferred delivery
state
yet.
100721 Fig. 7 shows the nebulizer 1 in a schematic section as well as
the
container 3 and housing part 18 which are still separated from the (upper part
of the) nebulizer 1.
100731 The nebulizer 1 or its housing or housing part 18 comprises
preferably a securing device 32 which may have different functions. The
securing device 32 may hold the container 3 such that the container 3 is
moveable back and forth within the completely closed housing for conveying
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 18 -
the fluid 2, pressure generation and/or nebulization, wherein the securing
device 32 may ensure that the container 3 is inseparable from the housing or
housing part 18. Thus, only complete replacement of the housing part 18
together with the respective container 3 is possible. Alternatively or
additionally, the securing device 32 may form the transportation lock 29.
Alternatively or additionally, the securing device 32 may prevent that the
used
container 3 and/or used housing part 18 can be (re)connected to or used with
the nebulizer 1 once more.
[0074] When the securing device 32 or transportation lock 29 is
closed,
the container 3 is held or counter-beared for opening by inserting the
conveying element or tube 9, preferably wherein a press-fit is formed between
the conveying element or tube 9 and the container 3 or closure part 27, and/or
for (completely) connecting the container (head) to the holder 6. With other
words, the transportation lock 29 or securing device 32 form preferably a
counter-bearing for the container 3 during closing of the nebulizer 1.
[0075] When the securing device 32 or transportation lock 29 is
closed,
the container 3 is held spaced from the piercing element 22.
[0076] The securing device 32 is preferably located or arranged or
fixed
at or in the housing part 18 as shown in Fig. 6 and 7.
[0077] Preferably, the securing device 32 comprises or consists of a
metal and/or stamped part and/or consists of a single, unitary part.
Preferably,
the securing device 32 is made of steel, in particular spring steel.
Preferably,
the securing device 32 is produced from sheet material by cutting, stamping or
the like and/or by bending. Preferably, the securing device 32 or a part
thereof

forms a cage, in particular encompassing the container 3 or an end portion
thereof, in particular the container base 21.
100781 Preferably, the securing device 32 comprises holding elements
33 and/or locking elements 34. The elements 33 and/or 34 are preferably
designed like arms, fingers, leaves or the like. In particular, the elements
33
and 34 are alternately distributed over the circumference of the container 3.
Preferably, the securing device 32 comprises multiple holding elements 33 and
multiple locking elements 34, in particular three or more holding elements 33
and three or more locking elements 34. Preferably, the elements 33 and 34
extend at least essentially axially and/or in the direction of the back and
forth
movement of the container 3 and/or in the direction of the longitudinal or
main
extension of the nebulizer 1 or main dispensing direction of the aerosol 14.
[0079] Preferably, the elements 33 and 34 are held by or connected
with
a base 35 of the securing device 32, as shown in Fig. 8. Fig. 8 shows the
nebulizer 1 in a schematic side view with already partly mounted housing part
18 and with some cut-away portions. The transportation lock 29 or securing
device 32 is still closed or locked, i.e. the container 3 is still securely
held so
that it cannot axially move (axially means in the direction of the back and
forth or stroke movements).
100801 Preferably, the securing device 32 or base 35 comprises or
holds
the piercing element 22 for piercing the container 3, i.e. opening the
container
base 21 or its venting hole 31 or a respective sealing of the container 3 or
the
like in the activated and tensioned state, i.e. when the container 3 reaches
its
lower end position. In the shown and preferred embodiment, the piercing
element 22 is formed by a respective bending of a spring portion 36 of the
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 20 -
securing device 32 or its base 35. The spring portion 36 can support or
facilitate the (complete or final) connection of the container 3 to the holder
6.
100811 The securing device 32 or base 35 comprises preferably at least
one or multiple fixing portions 37 for fixing the securing device 32 at or in
the
nebulizer 1 or housing or housing part 18. In particular, the fixing portions
37
may fix the securing device 32 when it is pressed into the housing part 18 by
cooperating with the sidewall of the housing part 18. However, it is also
possible to overmold the securing device 32, its base 35, the fixing portions
37
or the like. Moreover, the securing device 32 could be connected with the
housing part 18 or the like in any other suitable manner, in particular, by a
separate fixing member, by gluing or the like.
[00821 As already mentioned, the securing device 32 preferably forms
the transportation lock 29 for holding the container 3 unmovable in the
housing or housing part 18 in the delivery state of the nebulizer and/or
before
attaching the housing part 18 to the nebulizer 1. In this situation (in
particular
in the delivery state), the container 3 or a preferably radially protruding
and/or
circumferentially extending part or edge 38 thereof, preferably formed at the
container base 21, is held preferably in a form-fit manner and/or between the
holding elements 33 and locking elements 34, in particular between
respectively formed or bent end portions 33a and 34a of the elements 33 and
34, respectively, as shown in Fig. 6 to 8.
[00831 In the shown embodiment, the container 3 and/or edge 38 is
caught between the end portions 33a and 34a, preferably alternatively. The
holding elements 33 and/or end portions 33a grip or extend over the edge 38,
and the locking elements 34 or its end portions 34a grip or extend under the
edge 38, so that the edge 38 and container 3 are securely held in between, in

particular by form-fit, preventing any axial movement of the container 3
relative to the securing device 32 and relative to the associated housing part
18
in this state, i.e. with locked transportation lock 29 / securing device 32.
[0084] Preferably, the end portions 33a and/or 34a are formed like
claws or the like and/or extend preferably radially inwardly.
[0085] Preferably, the elements 33 and/or 34 can flex with its free
ends
radially outwardly.
[0086] Preferably, the securing device 32 is designed such that the
associated container 3 can be connected with the securing device 32 by a
respective axial force or movement, wherein the elements 33 and/or 34 flex
preferably automatically outwardly as required to receive the container 3 in
the locked position as shown in Fig. 6 to 8. However, if necessary, a suitable
tool (not shown) or the like could be used alternatively or additionally for
assembly if necessary.
[0087] For example, the ends of the end portions 33a could be inclined
such that the container 3 may be inserted into or connected with the securing
device 32 by a respective axial movement so that the holding elements 33 flex
outwardly to allow passing of edge 38.
[0088] Preferably, the holding elements 33 or its end portions 33a
prevent separation of the container 3 from the securing device 32 and, thus,
from the associated housing part 18 or the like.
[0089] In the present embodiment, the holding elements 33 extend
preferably above the end portions 33a and/or form or comprise preferably
CA 02834318 2013-10-24
WO 2012/162305

- 22 -
arm-like guiding and/or locking portions 33h. These axial extensions and/or
these portions 33b extend axially beyond the end portions 33a and/or may
cooperate with the container 3 or its edge 38 during axial assembly of the
container 3 with the securing device 32 such that the holding elements 33 are
flexed sufficiently outwardly so that the edge 38 can pass the end portions
33a
and the container base 21 can be seated on the end portions 34a of the locking
elements 34.
[0090] The locking elements 34 preferably comprise actuation portions
34b at its free ends extending axially beyond the end portions 34a. The
actuation portions 34b may radially guide the container 3 and/or facilitate
insertion of the container 3 or its edge 38 between the free ends of the
locking
elements 34 although the locking elements 34 are preferably radially inwardly
biased as well as the holding elements 33.
[0091] When, the container 3 is held with its edge 38 between the end
portions 33a and 34a, the transportation lock 29 / securing device 32 is
closed,
i.e. the container 3 cannot move axially within the housing part 18 or
nebulizer 1.
[0092] For opening the transportation lock 29 or securing device 32,
the
locking elements 34 and/or its end portions 34a are flexed preferably radially
outwardly so that the container 3 can freely move axially, in particular
restricted such that the edge 38 can only move axially within the securing
device 32 and/or that the axial movement is restricted (in the drawings
upwardly) by the holding elements 33 or its end portions 33b and/or such that
the container 3 cannot be separated from the securing device 32. This opening
of the transportation lock 29 or securing device 32 will take place when
activating the nebulizer 1, when using the nebulizer 1 for the first time
and/or
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969

when completely closing the nebulizer 1. Then, the container 3 can axially
move, in particular back and forth and/or with its edge 38 between the end
portions 33a and the piercing element 22 in the present embodiment. This
situation is schematically shown in the schematic section according to Fig. 9
which shows the nebulization with closed housing or housing part 18 and with
opened transportation lock 29 / securing device 32.
[0093] In Fig. 9, the container 3 is shown in its lower position
similar to
Fig. 4, in particular, wherein the container base 21 is in contact with the
piercing element 32. However, the nebulizer 1 is not shown in the tensioned
state, i.e. the holder 6 is not in its lower position, i.e. the holder 6 is
not yet
connected with the upper end or head of the container 3. Normally, the holder
6 would be connected to the container 3 in this situation with the container 3
in the lower position. With other words, usually the nebulizer 1 or drive
spring
7 would be tensioned in the situation with the container 3 being in the lower
position.
[0094] Preferably, the container is finally or completely or correctly
connected to holder 6 when tensioning the nebulizer 1 or its drive spring 7
for
the first time after completely closing the nebulizer 1. However, it is
generally
also possible that the nebulizer 1 is in the tensioned state, i.e. the drive
spring
7 is already tensioned and the holder 6 is in the lower position, before or
during (first) assembly with lower housing part 18. Consequently, the holder 6
should directly connect with the container 3 when completely closing the
housing part 18, and the situation shown in Fig. 9 should normally not occur.
[0095] In Fig. 9, the end portions 34a are moved radially outwardly in
order to open the transportation lock 29 or securing device 32. This is
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 24 -
achieved preferably by flexing the locking elements 34 radially outwardly.
This can be achieved in particular by acting on the actuation portions 34b.
100961 Preferably, the transportation lock 29 is opened or the locking
elements 34 are flexed outwardly when completely closing the nebulizer 1 or
its housing part 18, in particular by cooperation with or abutment of the
inner
part 17, its lower part 17b, a retaining part 39 and/or a securing part 40.
The
retaining part 39 is preferably arranged at the upper housing part 16 or inner
part 17. The securing part 40 is preferably arranged in the lower housing part
18.
100971 The retaining part 39 is connected to the lower or free end of
the
inner part 17 or its lower part 17b in order to hold, bear or support an end
(the
lower end) of the drive spring 7. Fig. 3 to 5 show a preferred construction of
the retaining part 39. It is preferably formed as a ring and/or provided with
hooks or the like for interconnection with the inner part 17. In the preferred
embodiment, the retaining element 19 forms a unitary component or portion of
the retaining part 39. However, other constructional solutions are possible.
100981 In the embodiment shown in Fig. 3 to 5, a preferably ring-like
securing part 40 opens the transportation lock 29, in particular flexible arms
of
the transportation lock 29, to allow axial movement of the container 3. This
securing part 40 keeps the transportation lock 29 or its flexible arms open
when the nebulizer 1 or its housing part 18 has been completely closed. The
securing part 40 is pushed axially downwards by abutment of the inner part 17
or retaining part 39 within the housing part 18 when completely closing the
nebulizer 1.

[0099] In the preferred embodiment shown in Fig. 6 to 15 and
particular
in Fig. 9, the nebulizer 1, housing part 18 or securing device 32 comprises
the
preferably ring-like securing part 40 for opening the transportation lock 29 /
securing device 32 or its locking elements 34. In particular, the securing
part
40 is pushed axially downwards when closing the nebulizer 1 so that it is
moved between the locking elements 34 or its actuation portions 34b and
exerts an axial force radially outwards. Preferably, an inclined plane
converts
the axial or closing movement into an opening or radial movement which
forces the actuation portions 34b radially outwardly when the securing part 40
is forced axially downwardly, here by abutment of the retaining part 39, in
particular in the axial end position shown in Fig. 9.
[0100] Preferably, the securing part 40 and/or locking elements 34 or
actuation portions 34b comprise a respectively inclined guiding surface 41 or
the like to convert the axial closing movement or movement of the securing
part 40 into the desired radial opening movement of the locking elements 34
or actuation portions 34b and, thus, of the end portions 34a to open the
transportation lock 29, in particular when the housing has been completely
closed or when the housing part 18 has been pushed completely on the
nebulizer 1.
[0101] However, other constructional solutions are possible to realize
opening of the transportation lock 29 or securing device 32 or its locking
elements 34 or end portions 34a when closing the nebulizer 1 or its housing
parts 18.
[0102] In the preferred embodiment the securing part 40 serves
alternatively or additionally another purpose. Namely, the securing part 40
prevents the locking portions 33b from moving radially apart or flexing
CA 02834318 2013-10-24
WO 2012/162305
PCT/US2012/038969
- 26 -
radially outwards before the nebulizer 1 is assembled with its housing part 18
for the first time.
[0103] As already mentioned, the securing device 32 prevents
preferably that a container 3 can be connected to or used with the nebulizer 1
once more. In particular, the securing device 32 can prevent that a used
housing part 18 or used container 3 can be reconnected to the nebulizer 1 once
it has been detached from the nebulizer 1. Thus, the securing device 32
prevents any undesired reuse of the container 3 and/or housing part 18 with
its
preferably inseparable container 3.
[0104] In the present embodiment, the undesired reuse is prevented in
that the locking portions 33b force apart or move apart or radially and/or
outwards at least after the used container 3 and/or housing part 18 has been
detached from the nebulizer 1 such that the used container 3 and/or housing
part 18 cannot be connected to or used with the nebulizer 1 once more.
Preferably, the locking portions 33b are biased such that the locking portions
33b force apart or move radially and/or outwards after release.
[0105] In the preferred embodiment, the locking portions 33b are held
together or held against moving apart, radially and/or outwards by the
securing part 40 (schematically indicated in Fig. 7) before the container 3
and
the associated housing part 18 have been connected to the nebulizer 1 for the
first time. In this pre-assembly state, the securing part 40 is located
preferably
near the free ends of the locking portions 33b and/or it encompasses that
locking portions 33b such that locking portions 33b are held sufficiently
close
together to be inserted with its free ends within the retaining part 39 and/or
drive spring 7 when pushing the housing part 18 axially onto the nebulizer 1
or its inner part 17, in particular lower part 17b.

WO 2012/162305 PCT/US2012/038969
- 27 -
[0106] The securing part 40 may cooperate with the locking portions
33b or protrusions 33c thereof (shown in Fig. 9) preferably such that the
securing part 40 is held by a preferably radial engagement and/or frictional
force in its (upper) position holding the locking portions 33b or holding
elements 33 together in the pre-assembly state. Later during assembly, in
particular during complete closing of the housing or pushing on the housing
part 18, the locking portions 33b are moved within the retaining part 39 and
drive spring 7, while the securing part 40 is moved axially downwards or
towards the securing device 32, the container base 21 and/or bottom part of
the end of the housing part 18. Then, the end position or completely assembled
position is reached as shown in Fig. 9. In this state, the radially biased
locking
portions 33b are held together by the drive spring 7 as the securing part 40
does not hold the locking portions 33b together any more.
101071 Preferably, the securing part 40 has opened the transportation
lock 29 or locking elements 34 in the last part of the closing movement or
just
when completely closing the nebulizer 1 as already mentioned.
[0108] The schematic section of Fig. 10 shows the housing part 18
together with its associated container 3 after it has been used and separated
from the nebulizer 1. The securing part 40 remains preferably in its lower
position. The transportation lock 29 is (still) open. The container 3 is shown
in
its upper position where it is held by the end portions 33a of the holding
elements 33 when detaching the container 3 from the nebulizer 1, in particular
from the holder 6 and the conveying element or tube 9.
101091 Fig. 10 shows that the locking portions 33b have been forced
apart, in particular due to its biasing or elastic force, here moved radially
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 28 -
outwardly with its free ends in particular due to its preferably radial
biasing or
elastic force. This forced apart position of the locking portions 33b blocks
reconnection of the container 3 and/or housing part 18 and/or securing device
32 with the nebulizer 1. Thus, the already used container 3 cannot be reused.
Thus, misuse of the container 3 or nebulizer 1 can be prevented.
101101 The securing part 40 may additionally secure the holding
elements 33 or its end portions 33a against radial opening when the securing
part 40 is in its lower position as shown in Fig. 9 and 10. In this case, the
securing part 40 contacts the holding elements 33 preferably on the outer side
to prevent or restrict any outward flexing. Thus, the securing device 32 or
its
holding elements 33 or end portions 33a are secured against opening so that
the container 3 or its edge 38 is securely held within the securing device 32
or
the cage formed by the securing device 32 or holding elements 33.
[0111] In the preferred embodiment, the counter device 23 is arranged
preferably at the housing part 18 as schematically shown in Fig. 7 to 10. The
counter device 23 counts the actuations or operations of the nebulizer 1 or
the
discharged doses. Preferably, the counter device 23 counts actuations or
operations by detecting the rotation of the inner part 17 relative to the
upper
part 16 of the housing. With other words, the counter device 23 may count the
tensioning the nebulizer 1 or its drive spring 7. However, other
constructional
solutions are possible.
[0112] Preferably, the counter device 23 comprises a threaded spindle
or shaft 42 with an associated, preferably unitary formed drive gear 43. The
counter device 23 comprises preferably further a rider 44 associated to the
threaded shaft 42 and cooperating with the threaded shaft 42 such that the
rider 44 is axially moved along the threaded shaft 42 as the shaft 42 is
rotated.

[0113] The threaded shaft 42 is rotably beared preferably in the lower
housing part 18 and/or extents preferably parallel to the axial or
longitudinal
direction of the nebulizer 1 and/or to the axial or stroke movement of the
container 3.
101141 The drive gear 43 is located preferably at an upper end of the
threaded shaft 42 and/or housing part 18, in particular such that it can mesh
with a preferably inner toothing 45 of the housing or upper housing part 16 of
the nebulizer 1 in the assembled state, i.e. when the housing of the nebulizer
1
is completely closed, as schematically shown in Fig. 9.
101151 The counter device 23 or its rider 44, in particular the axial
position of the rider 44 along the threaded shaft 42, may show or indicate the
number of operations, in particular of tensioning, actuations or doses, which
have already been performed or used with the current container 3 or which can
still be performed with the current container 3. This operation number can in
particularly been shown by a pointer 46 and/or an associated scale or the like
which are visible reasonable through a corresponding window or transparent
part of the housing part 18. It has to be noted that the number has not be
shown precisely. In particular, it may be sufficient that the counter device
23,
the rider 44 or its pointer 46 give a rough indication of the number. For this
purpose, it may be sufficient if the scale shows only different coloured areas
or regions roughly indicating said number. Further, it has to be noted that
other constructional solutions are possible as well.
101161 The counter device 23 works preferably mechanically. This
allows a very simple and robust construction and a very secure operation.

WO 2012/162305 PCT/US2012/038969
- 30 -
[0117] The counter device 23 may control or provide preferably locking
of the nebulizer 1, indicating any required container replacement and/or
container counting. For this purpose, the monitoring 23 or the rider 44
comprises preferably an actuation part 47 as schematically shown in Fig 8.
The actuation part 47 is preferably ridge-like and/or extending in axial
direction and/or towards the upper housing part 16 and/or upwards.
[0118] The counter device 23 is associated to the respective housing
part 18 and, thus, preferably to only one container 3 and counts operations of
the nebulizer 1 with the respective container 3, i.e. counts (only) the number
of doses of fluid 2 removed or still removable from this container 3.
[0119] It has to be noted that the first container 3 may be pre-
installed
together with the associated housing part 18 in the delivery state. This pre-
installment is optional. Preferably, further separate containers 3 are
delivered
together with the nebulizer 1, wherein each container 3 is inseparably
connected with an associated housing part 18 and, thus, with an associated
counter device 23. Preferably, the counter device 23 or threaded shaft 42 of
each housing part 18 is designed or provided with inhibition or brake means,
such that any undesired counting or rotation is prevented before the
respective
housing part 18 is mounted to the nebulizer 1.
[0120] The nebulizer 1 comprises preferably a device 48 for counting
the number of containers 3 that have been used or still can be used with the
nebulizer 1 and/or for indicating or displaying said container numbers and/or
symbols indicating container replacement and/or end of use. This device 48 is
preferably for monitoring and/or user guidance.

[0121] Preferably, said numbers and/or symbols are visible or shown
through a transparent part or window 49 of the nebulizer 1, in particular
located in the upper housing part 16 as schematically indicated in Fig. 6. In
particular, said numbers and/or symbols are shown at a side face of the
nebulizer 1. Other arrangements or constructional solutions are possible.
[0122] Fig. 11 shows the nebulizer 1 without lower housing part 18 and
without container 3 in a schematic side view, wherein parts of the upper
housing part 16 have been cut-away so that the monitoring or guidance device
48 of the nebulizer 1 is better visible.
[0123] The nebulizer 1 or device 48 comprises preferably a member 50
for indicating or displaying said container number, symbols, a status, and/or
user instructions, e.g. relating to container replacement, and/or for
controlling
locking of the nebulizer 1. Thus, the member 50 is also called indicator
member and/or control member. Preferably, both functions are achieved by the
same or one single member 50. However, it is also possible that the indicator
member and the control member are formed by separate parts or multiple
parts. Preferably, the following description shall be understood in such a
broad
sense.
[0124] Preferably, the nebulizer 1 or device 48 comprises a spring 51
for driving or moving, in particular rotating, the member 50. This spring 51
is
shown in Fig. 7, 8, 9 and 11. Preferably, the member 50 is driven or rotated
¨ in particular in multiple steps and/or from an initial (rotational) position
to a
final (rotational) position ¨ only by spring force or by means of the spring
51.

[0125] The spring 51 is preferably a helical, sleeve-like, ring-like
and/or
torsional spring and/or a leg spring. It is preferably located coaxially with
and/or adjacent to the driven member 50
[0126] The spring 51 is preferably mounted in a biased state so that
it
applies a rotational force to the member 50. For this purpose, the spring 51
is
supported with one end or leg at the nebulizer 1, in particular at the upper
housing part 16, and engages with its other end or leg with member 50, e.g. by
abutting a respective shoulder or bearing portion 67 (shown in Fig. 12 and 13)
of the member 50 or the like.
[0127] Fig. 12 shows a preferred embodiment of the member 50 in a
schematic side view. Fig. 13 shows the member 50 in a perspective view.
[0128] The member 50 is preferably formed by a unitary and/or molded
part. The member 50 is preferably at least essentially ring-like and forms or
comprises a preferably closed ring.
[0129] The member 50 comprises or is provided with numbers 52
indicating said container number, and/or with said symbols 53 for user
guidance, in particular for indicating container replacement and/or end of use
of the nebulizer 1. Preferably, the numbers 52 and symbols 53 are shown
and/or arranged on the member 50 such that one or more numbers 52 and one
or more symbols 53 alternate. In particular, between preferably consecutive
numbers 52 one or more symbols 53 are arranged and/or shown such that
these symbols 53 indicate e.g. necessary container replacement, opening of the
nebulizer 1, closing of the nebulizer 1 or the like. This may be communicated
or indicated by respective arrows, colours, marks or the like as symbols 53.
Further, the last symbol 53 may indicate end of use of the nebulizer 1 or
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969

complete locking of the nebulizer 1, e.g. by an "X" or the like. This symbol
53
may be shown for example when the allowable number of operations or
actuations of the nebulizer 1 have been reached or exceeded of the last
container 3 that may be used with or in the nebulizer 1, i.e. indicating total
or
final locking of the nebulizer 1. I n the present embodiment, preferably a
sequence of at least two different symbols 53 is shown between different or
consecutive numbers 52. This sequence of symbols 53 comprises preferably a
first symbol 53 (e.g. arrow downwards) indicating opening of the nebulizer 1
for container replacement and a second symbol 53 (e.g. arrow upwards)
indicating closure of the nebulizer 1 for completing container replacement.
However, it is also possible to show only one, potentially similar or
identical
symbol 53 between the different or consecutive numbers 52, such as one
symbol 53 indicating container replacement. Preferably, only one special or
end symbol 53, such as "X", is shown at the end when the allowable number
of operations or actuations of the nebulizer 1 has been reached or exceeded
for
the last container 3 and/or when the nebulizer 1 is finally blocked and/or
when
no further container 3 can be inserted.
[0130] The member 50 comprises preferably engagement or stop
portions 54 which are preferably formed by radial protrusions or the like in
the
present embodiment. The stop positions 54 are used preferably to allow or
realize a stepwise movement or rotation (indexing) of the member 50.
f01311 The member 50 comprises further preferably blocking portions
55 which extend preferably axially and/or cooperate with the retaining element
19 to selectively lock the nebulizer 1 or housing part 18 against opening, in
particular by selectively blocking the retaining element 19 against depressing
or radial inward movement.

WO 2012/162305 PCT/US2012/038969
- 34 -
[0132] The member 50 comprises preferably control portions 56 for
controlling or driving an associated lock 57 of the nebulizer 1. The control
portions 56 are formed preferably by protrusions or indentions or inclined
guiding surfaces or the like which preferably extend radially and/or which are
preferably formed on an outer circumference of the member 50 or its ring
portion. However, other arrangements are possible as well.
[0133] The lock 57 is preferably formed by a locking member 58 or a
portion 59 thereof, which is preferably tongue-like, leaf-like and/or
flexible.
Fig. 14 shows in a perspective view the locking member 58. Fig. 15 shows in
other perspective view the locking member 58.
[0134] The locking member 58 is preferably made of metal and/or
formed by plate material and/or a stamped part or the like. The locking
member 58 is preferably ring-like and/or sleeve-like.
[0135] The portion 59 is preferably bent or indented or provided with
such a form, in particular in radial direction and/or provided with a crimp,
corrugation 60 or the like, for cooperating with the member 50 and/or at least
one or more or all of the control portions 56, in particular such that
depending
on the rotational movement or position of the member 50 the portion 59 is
radially flexed, in particular outwards, or not. For example, the control
portions 56 are indented or recessed so that a portion 59 is not flexed
radially
outwards if the respective corrugation 60, which extends radially inwards from
the respective portion 59, is received in a portion 56 located adjacent to
this
corrugation 60 on the inner side. If the member 50 is in another rotational
portion, the corrugation 60 may abut on the non-recessed outer periphery of
member 50 so that the respective portion 59 is flexed outwards and the lock 57
is closed. Thus, the lock 57 is driven or controlled, namely closed and
opened,
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 35 -
by means of the control member 50, in particular depending on its rotational
position.
[0136] As already mentioned, the device 48 or member 50 is preferably
driven by spring force, in the present embodiment by the force of spring 51.
In
particular, the member 50 is rotated or indexed stepwise by means of the force
of the spring 51, wherein a ratchet or stop mechanism is provided to ensure
the
only stepwise moving or rotating of the member 50. In particular, stop means
engage with the stop portions 54 of the member 50. In the present
embodiment, the mechanism or stop means are preferably formed by one or
two stop elements 61. The stop elements 61 are preferably formed like arms
and/or by the locking member 58. The stop elements 61 are preferably
elastically flexible to selectively allow a stop portion 54 to pass, i.e. to
selectively allow the member 50 to index one step further, or to block a stop
portion 54 and, thus, member 50 against further rotation. Preferably, the stop
elements 61 are biased into a stopping position such that each stop element 61
extends into the way of movement of the stop portions 24 such that no stop
portion 54 can pass the respective stop element 61.
[0137] Preferably, at least two stop elements 61 are provided and
preferably offset such that stop elements 61 can be actuated alternatively to
allow the member 50 to index or move further by one step, i.e. by one
rotational movement or increment when the stop elements 61 are alternatively
actuated, e.g. flexed, in particular in axial and/or radial direction, to
allow one
stop portion 54 to pass. The stop elements 61 are preferably flexed upwards to
allow the respective stop portion 54 to pass. The actuation of the stop
elements
61 will be explained in more detail below.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 36 -
[0138] The stop elements 61 or its free ends may be provided with a
broadened abutment or engagement body or surface, in particular by
respectively bending the element or arm 61, by overmolding or the like. Each
stop element 61 may be provided with a contact element 61a as schematically
shown in Fig. 8. The contact element 61a may be formed by overmolding
and/or may be schoe-like. The contact element 61a may form a stop or
abutment for the stop portions 54 such that the member 50 is blocked against
further rotation by force of spring 51 when the stop element 61 or contact
element 61a is in the blocking position, here in the lower position shown in
Fig. 8 where one stop portion 54 abuts the contact element 61a and can not
pass in circumferential direction. Here, the stop element 61 or contact
element
61a has to be moved upwards or axially so that the blocked stop portion 51
can pass and the member 50 can index one step further in circumferential
direction.
[0139] In the following, the operation and handling of the nebulizer
1
will be explained in more detail.
[0140] The nebulizer 1 may be delivered with a pre-installed
container
3 and pre-attached housing part 18. In this case, the nebulizer 1 or its
housing
part 18 is not completely closed so that the container 3 is not yet
fluidically
connected or opened.
[0141] Alternatively the nebulizer 1 may be delivered with a separate
container 3 and housing part 18. In this case the container 3 and the housing
part 18 are preferably pre-assembled, i.e. form a unit that is separate from
the
nebulizer 1.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 37 -
[0142] In any case, the nebulizer 1 is preferably delivered together
with
multiple containers 3, e.g. four or five containers 3, wherein each container
3
is inseparably connected to an associated housing part 18. These units of
containers 3 and housing parts 18 can be exchanged so that the nebulizer 1 can
be used with multiple containers 3 one after the other.
[0143] In both cases, the container 3 is preferably held unmoveably
at
or within the housing part 18 by the closed transportation lock 29 or securing
device 39.
[0144] In both cases, the housing part 18 comprises preferably a
coding,
e.g. by one or more grooves, protrusions, ribs 62 or the like distributed
around
the inner circumference of the housing part 18 and/or axially extending, as
schematically indicated in Fig. 10. This coding corresponds to the container 3
or the respective fluid 2 associated to the housing part 18. The coding
matches
to a complementary coding at the nebulizer 1, in particular at the inner part
17
or retaining part 39, and is preferably formed by respectively arranged and/or
dimensioned indentions, coding portions 63, such as protrusion, indentions,
recesses or the like, in particular formed by or at the retaining ring or part
39,
as schematically shown in Fig. 11. Only when the codings match, the housing
part 18 and, thus, the container 3 can be pre-installed and/or (completely)
connected to or with the nebulizer 1.
[0145] Before (completely) closing the nebulizer 1 or its housing
part
18, the device 48 or indicator member 50 may indicate by a respective symbol
53, such as an arrow pointing upwards, to completely close the nebulizer 1 or
housing pail 18.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 38 -
[0146] When the housing part 18 is completely closed, the container 3
associated to the housing part 18 is fluidically connected to the nebulizer 1.
This is detected or registered by the nebulizer 1 or device 48. This detection
of
the connection of the housing part 18 and, thus, of an associated container 3
is
preferably realized mechanically, in particular by actuating one of the stop
elements 61 to allow the member 50 to index one step further, i.e. until the
other stop element 61 stops further indexing or rotation of the member 50. In
the present embodiment, this registration or actuation is preferably achieved
by a protrusion 64 formed at the housing part 18, in particular at its upper
front face, as shown in particular in Fig. 7. When completely closing
nebulizer
1, the protrusion 64 abuts one associated stop element 61 or contact element
61a and consequently flexes the stop element 61 or contact element 61a
upwards such that it does not stop a corresponding stop portion 54 of the
member 50 any more, but allows the member 50 to move or rotate one step
further, i.e. until the other stop element 61, which has not been flexed out
of
engagement in this state, stops further rotation by stopping a corresponding
stop portion 54, preferably another one of stop portions 54.
[0147] As already mentioned, the container 3 is preferably
inseparable
from the housing part 18, the associated counter device 23 and/or associated
securing device 32. Thus, after connection of a new container 3 with the
nebulizer 1, the associated counter device 23 starts counting of the number of
operations or uses of the respective container 3 that have already been
performed or still can be performed. This operation number may be indicated
or shown by the counter device 23 or its rider 44 or pointer 46 as already
mentioned, while the device 48 or member 50 preferably only shows the
container number 52, i.e. the number of containers 3 that have already been
used or still can be used with the nebulizer 1.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 39 -
[0148] Preferably, the nebulizer 1 is blocked against opening until
the
current container 3 has been (sufficiently) emptied, and/or until a
predetermined number of operations or actuations has been reached or
exceeded. This blocking of the nebulizer 1 or its housing part 18 against
opening and/or container replacement is preferably achieved by a respective
blocking portion 55 of the member 50 located below the retaining element 19
in this state as schematically indicated e.g. in Fig. 9, such that the
retaining
element 19 cannot be depressed, i.e. the nebulizer 1 cannot be opened and the
housing part 18 cannot be detached.
[0149] When a predetermined number of operations or actuations of the
nebulizer 1 has been reached, the nebulizer 1 is blocked against further use
with the current container 3. This blocking is also called first locked state.
[0150] The first locked state is entered preferably by means of the
counter device 23. In particular, the rider 44 or its actuation part 47
cooperate
with the device 48 to enter the first locked state, when a predetermined
number of operations have been reached or exceeded with the current
container 3. Particularly, the rider 44 or its actuation part 47 reach an
upper
axial position in this state and actuate a respective stop element 61 or
contact
element 61a that is in blocking position or engagement with a stop portion 54.
Thus, the stop element 61 or contact element 61a is preferably flexed or
deformed such that the previously stopped stop portion 54 can pass and the
member 50 is free to index one step further by the force of spring 51. Fig. 8
shows a situation, in which the rider 44 and actuation part 47 are already
near
the upper position and near the position to actuate the associated stop
element
61 or contact element 61a. However, in the state shown in Fig. 8 one stop
portion 54 and the member 50 are still blocked against rotating one step
further.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 40 -
[0151] The above indexing of the member 50 by one step leads to the
first locked state. In this state, the nebulizer 1 or retaining element 19 is
unblocked so that it can be opened. In particular, the blocking portion 55
blocking actuation of the retaining element 19 in the previous state is moved
further, so that the retaining element 19 is not blocked any more, but can be
actuated or pushed in order to allow detachment of the housing part 18 for
container replacement.
[0152] In the first locked state the nebulizer 1, device 48 or member
50
indicates preferably by a respective symbol 53, in particular by an arrow
pointing downwards, that container replacement is necessary and/or that the
nebulizer 1 is locked against further use with the current container 3.
[0153] By the above indexing of the member 50 to reach the first
locked
state, the nebulizer 1 is locked against further use. This is achieved in
particular in that the member 50 drives the lock 57 to lock the nebulizer 1
against further actuation, preferably against further tensioning of the drive
spring 7 and/or against rotating of the housing part 18. This is preferably
realized in that the rotation of the member 50 flexes the lock 57 or portion
59
of the locking member 58 radially outwards so that the flexed portion 59
leaves its non-locking position, into which it is biased, and locks further
rotation of the inner part 17 relative to the upper housing part 16. This
locking
is in particularly achieved in that a free end of the portion 59 engages into
a
respective toothing or against respective abutment surfaces formed at the
inner
surface of the upper housing part 16. In this respect it has to be noted that
the
device 48 is preferably arranged or mounted on inner part 17, particular on
its
upper part 17a, wherein the preferably ring-like locking member 58 is
preferably arranged around the rotatable member 50. The locking member 58
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 41 -
is preferably secured against rotation relative to the inner part 17 by
respective
form fit engagement, preferably of the inner part 17 or at least one
protrusion
17c thereof into a recess 65 of the locking member 58. In the present
embodiment, the recess 65 is preferably formed like a pocket or a portion cut-
out of the periphery from one axial side. In particular, the locking member 58
may be provided with two or more recesses 65 as schematically shown in Fig.
14 and 15, for engagement of respective protrusions 17c or the like, in
particular of the associated inner part 17. However, other constructional
solutions are possible as well.
101541 Consequently, only member 50 is rotatable relative to inner
part
17 and, thus, to locking member 58. However, locking member 58 is rotatable
together with inner part 17 relative to upper housing part 16.
101551 As already mentioned, the control member 50 is moveable, in
particular rotatable, relative to locking member 58. This relative rotation is
meant when any rotation or indexing of the control member 50 is mentioned.
In this context, it has to be considered that the device 48 and the locking
member 58 are rotated together with the inner part 17, but this rotation is
different as this is the movement for tensioning the energy store, here spring
7,
and/or for delivering or sucking fluid 2 out of the container 3 by in
particular
axial movement of the conveying element or tube 9.
101561 The construction mentioned above, results in that the device 48
is rotated together with the inner part 17 each time the lower housing part 18
is
rotated, i.e. when tensioning the drive spring 7. This rotation is preferably
performed in 180 steps. Therefore, the device 48 or indicator member 50
comprises preferably two sets of respective number 52 and/or symbols 53 that
are shown alternately through the window 49.
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 42 -
[0157] Thus, the member 50 comprises preferably two groups of
numbers 52 and/or symbols 53, each group with the respective sequence of
numbers 52 and/or symbols 53, wherein the groups are arranged offset by
180 on the member 50. This offset correspondence to the rotational angle for
each rotational actuation of the lower housing part 18 and inner part 17 for
tensioning the nebulizer 1 / drive spring 7.
101581 Preferably, the control portions 56 and/or the peripheral
parts of
the control member 50 inbetween the portion 56 form an inclined or control
plane or surface cooperating with the portion 59 or its cam or corrugation 60
such that the lock 57 or the locking can be actuated alone by the force of the
spring 51 acting on the member 50. In particular, the spring 51 or member 50
drives the lock 57. Further, the member 50 controls the lock 57 or the
locking.
As the member 50 also forms an indicator member, the indicator member
drives the lock 57 or locking as well.
101591 In the present embodiment, the locking member 58 is preferably
arranged outside or around the control member 50 at least around a cylindrical
main part of control member 50. In particular, the locking member 58
encompasses or covers at least substantially the cylindrical main part of the
control member 50. The locking member 58 comprises preferably two
openings 66 (shown in Fig. 14 and 15) that are alternately aligned with
window 49 depending on the rotational position of inner part 17 and, thus, of
the locking member 58 so that the respective number 52 and/or symbol 53 is
visible through the window 49 and through locking member 58.
101601 In the first locked state, the member 50 is preferably stopped
against further rotation by the protrusion 64 where any other part
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 43 -
corresponding to the attachment of the housing part 18. When the housing part
18 is detached from the nebulizer 1 or its upper housing part 16 or inner part
17 for container replacement, this detachment is registered by unblocking the
further movement or rotation of the member 50. In particular, a stop portion
54 of the member 50 which has been stopped by protrusion 64 or the like, can
pass after detachment of the housing part 18 so that the member 50 can index
one step further. In this further rotational position, the nebulizer 1 is
still in its
first locked state, i.e. is still locked against further use, in particular
against
further actuation or tensioning of the drive spring 7. However, the member 50
may show the next symbol 53, in particular an arrow pointing upwards,
indicating that a new container 3 has to be connected and/or that a new
housing part 18 has to be connected to the nebulizer 1. This situation
correspondents to the initial situation before first assembly of the nebulizer
1
with the housing part 18 as already described.
[0161] It has to be noted that the blocking element 8 is preferably
blocked against actuation, in particular against release of the holder 6 and
drive spring 7 in the first locked state. This actuation locking will also be
achieved by the device 48 or member 50.
101621 When the housing part 18 and the associated container 3 have
been replaced, this is registered by the device 48, in particular by actuation
of
the corresponding stop element 61 by means of the protrusion 64. Then the
member 50 indexes one step further and shows the next container number 52.
Then, the lock 57 is reset, i.e. opened or unlocked again. Thus, the nebulizer
1
is unlocked and can be used further with the new container 3. Simultaneously,
the container 3 or housing part 18 is preferably locked again against opening
or container replacement, in particular in that the next blocking portion 55
is
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 44 -
positioned below retaining element 19 to prevent actuation of the retaining
element 19 which is necessary for opening the nebulizer 1.
[0163] The above sequence can be repeated, i.e. new containers 3 and
new housing parts 18 can be used one after the after with the nebulizer 1,
wherein the device 48 or indicator member 50 displays or shows the container
number 52 and, preferably, symbols 53 for user guidance, in particular to
indicate any necessary container replacement and/or indicating to open and
close the nebulizer 1 or the like. The container number 52 relates in
particular
to the number of containers 3 that have already been used with the nebulizer 1
or still can be used with the nebulizer 1. In particular, one or more symbols
53
are displayed or shown alternately with the consecutive container numbers 52.
This is realized preferably by one comment component, namely indicator
member 50. However, other constructional realizations are possible.
[0164] Further, the display of the container numbers 52 and/or symbols
53 works preferably only mechanical.
[0165] In particular, the device 48 and/or the lock 57 work only
mechanical.
[0166] After a predetermined number of containers 3 have been
connected to or with the nebulizer 1, the nebulizer 1 will be blocked against
further container replacement. After using the lastly inserted or connected
container 3, the nebulizer 1 will enter the final locked state, i.e. the
second
locked state, preferably where the lock 57 or nebulizer 1 is blocked against
resetting and/or the nebulizer 1 or housing part 18 is blocked against
opening.
This second locked state is entered in particular after the predetermined
number of operations has been reached or exceeded with the ultimate, current
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 45 -
container 3. Similar to the previous process the counter device 23 or its
rider
44 or actuation part 47 actuates the device 48, in particular the
corresponding
stop element 61 to allow to index the member 50 one step further into its
final
rotational position. Thus, the second locked state is entered.
101671 In the second lock state, the control member 50 can not be
rotated any further. This is realized in the present embodiment in particular
in
that the bearing portion 67 abuts one protrusion 17c of the inner part 17
engaging into one of the recesses 65. However, other constructional solutions
are possible in order to realize the desired rotational stop or blocking for
the
control member 50 in the final rotational position, i.e. in the second locked
state.
101681 In the second locked state, the device 48 or member 50 does
not
allow opening of the nebulizer 1 or housing part 18 as it would be in the case
in the first locked state. Instead, the member 50 comprises a respectively
designed, preferably sufficiently long blocking portion 55 to block the
retaining element 19 further against actuation and, thus, to block the
nebulizer
1 against opening and container replacement.
101691 In the second locked state, the nebulizer 1 can be locked
against
further actuation, in particular against tensioning of the drive spring 1
and/or
rotation of the housing part 18 or inner part 17. This can be realized by
actuating the lock 57, in particular by flexing portion 59 radially
(preferably
outwards) by the member 50 or its corresponding control portion 56. In the
second locked state, the nebulizer 1 is preferably locked against any further
discharge of fluid 2, in particular by blocking actuation of the blocking
element 8. This is preferably also realized by device 48.

[0170] Therefore, the nebulizer 1 cannot be used anymore after the
second locked state has been entered. The second locked state is not
reversible. In particular, resetting or unlocking of the lock 57 is not
possible,
but prevented in the second locked state.
[0171] As already outlined above, some general aspects or ideas of
the
nebulizer 1 according to the preferred embodiment can be summarized as
indicated in the following.
101721 The device 48 consists preferably only of two parts (control
member 50 and locking member 58) or three parts (control member 50, spring
51 and locking member 58), but provides multiple functions, in particular
displaying of numbers 42 and/or symbols 53 and/or user instructions, locking
of the nebulizer 1 against further use, locking of the nebulizer 1 against
tensioning, and/or locking of the nebulizer 1 against opening or container
replacement.
[0173] The nebulizer 1 may comprise the indicator member 50 for
showing numbers, in particular container numbers 52 and alternately symbols
53 indicating container replacement and/or nebulizer opening and/or closing.
101741 The indicator member 50 may be moved or rotated stepwise by
the force of the spring 51.
[0175] The indicator member 50 may drive the lock 57 of the nebulizer
1 such that the nebulizer 1 is locked against further use in the first locked
state, when he container 3 has to be replaced, wherein the first locked state
is
reset by indexing the indicator member 50 and/or resetting the lock 57 if the
container 3 and/or housing part 18 have been replaced.

[0176] The indicator member 50 is preferably ring-like.
[0177] The indicator member 50 works or shows the numbers 52 and/or
symbols 53 mechanically.
[0178] The nebulizer 1 comprises preferably the lock 57 for locking
the
nebulizer 1 against further use in the first locked state, in particular when
the
container 3 has to be replaced.
[0179] Preferably, the first locked state is reset by resetting the
lock 57,
if the container 3 and/or housing part 18 have been replaced. With other
words, the lock 57 is preferably resetable and can be used further after
container replacement. In particular, an exchange or replacement of the lock
57 is not necessary to reuse the nebulizer 1.
[0180] The nebulizer 1 comprises preferably the control member 50 for
controlling or driving the lock 57.
[0181] The control member 50 is preferably moved or rotated stepwise
by the force of the spring 51.
[0182] The lock 57 and/or first locked state is preferably blocked
against resetting in the second locked state.
[0183] The second locked state is preferably entered when a
predetermined number of containers 3 has been used or inserted into the
nebulizer 1 and, preferably after a predetermined number of operations has
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 48 -
been performed or exceeded with the nebulizer 1 after inserting the last
container 3.
101841 The control member 50 is preferably ring-like.
101851 Preferably, the control member 50 forms the indicator member
or vice versa.
101861 The control member 50 displays preferably the numbers 52 of
containers 3 that have been used or still can be used and/or the symbols 53
indicating containing replacement and/or user guidance or nebulizer handling.
101871 The control member 50 blocks preferably opening of the
nebulizer 1 and/or container replacement until a predetermined number of
operations has been reached or exceeded with the current container 3.
101881 Preferably, the nebulizer 1 is locked against opening or
container
replacement, in particular by means of the control member 50, in the second
locked state.
[0189] Preferably, the nebulizer 1 is locked against opening or
container
replacement, in particular by means of the control member 50, before the first
locked state has been reached.
101901 Preferably, the lock 57 locks the nebulizer 1 in the first
and/or
second locked state against conveying fluid 2 into the pressure generator 5
and/or against tensioning of the drive spring 7 of the nebulizer 1 and/or
against
rotation or turning of the housing part 18 or inner part 17.

[0191] Preferably, the housing part 18 has to be replaced each time
the
container 3 is replaced. In particular, the container 3 is inseparable from
the
housing part 18 and/or counter device 23 or vice versa.
[0192] The securing device 32, in particular its moved apart locking
portions 33b, preferably prevent that the used and/or detached container 3 can
be re-connected to or reused with the nebulizer 1 once more and or prevent
that a used or detached housing part 18 can be reconnected to the nebulizer 1
once more.
[0193] Preferably, the housing part 18 can be or has to be detached
or
opened for replacing the container 3.
[0194] Preferably, the securing device 32 is associated to the
container
3 preventing that a used container 3 can be connected or used with the
nebulizer once more.
[0195] Fig. 16 shows in a schematic exploded view a modified
embodiment of the nebulizer 1 with a preferred coding of the housing part 18
and of the nebulizer 1, in particular of the upper part 16 or inner part 17,
preferably by the retaining part 39, as already been mentioned above. The
modified embodiment deals with a preferred realization of the coding.
[0196] In the modified embodiment, the coding of the housing part 18
and, thus, of the container 3 and/or fluid 2, is realized by at least one
insert or
coding element 68, in the present embodiment by two or multiple inserts or
coding elements 68, which are mounted or fixed at or in the housing part 18.

[0197] In the following, a preferred realization and/or mounting of
one
or multiple or all coding elements 68 is discussed.
[0198] Preferably, the coding element(s) 68 can be clipsed into the
housing part 18. However, other constructional solutions are possible for
fixing the coding element(s) 68 at or in the housing part 18.
[0199] In the present embodiment, the housing part 18 comprises
preferably radial shoulders 69 for receiving or holding the coding elements
68.
In particular, the radial shoulders 69 are rib-like. Preferably, the coding
element 68 can be received between two spaced shoulders 69. In particular,
the coding element 68 can be pushed axially into the housing part 18.
[0200] Preferably, the coding element 68 can be arranged at the inner
side of the peripheral wall of the housing part 18. Preferably, the coding
element 68 is essentially plate-like and/or curved for arrangement within the
preferably essentially sleeve-like portion of the housing part 18.
[0201] The coding of the housing part 18 is provided or formed by the
one or more coding elements 68. This coding is associated to the container 3
which is preferably inseparably connected to or with the housing part 18.
[0202] Further, the nebulizer 1 is also provided with a coding. This
coding may be formed by the inner part 17, the retaining part 39, the coding
portion(s) 63 and/or a key element 70. Preferably, the key element 70 is ring-
like and/or provided with one or more or all coding portion(s) 63. Preferably,
the key element 70, which is shown in Fig. 16, forms part of the nebulizer 1
and/or is in particular inseparably mounted or fixable to the nebulizer 1.
Preferably, the key element 70 can be attached to the inner part 17 and/or to
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969
- 51 -
the retaining part 39. Preferably, the key element 70 can be attached to the
nebulizer 1 or inner part 17 or retaining part 39 by clipsing and/or in any
other
suitable manner.
102031 In particular, the key element 70 allows easy coding of the
nebulizer 1.
[0204] Preferably, the key element 70 is inseparable from the
nebulizer
1.
[0205] Preferably, the nebulizer 1 is coded by the peripheral
location
and/or extension and/or radial extension or dimension, inner or outer contour
or the like of the coding portion(s) 63.
102061 It has to be noted that the retaining element 39 and/or the
key
element 70 can be provided with the coding portion(s) 63.
102071 In the shown embodiment, the key element 70 can be clipsed or
attached to the retaining part 39. For this purpose, the key element 70
comprises preferably at least one or two holding portions 72 which can be
axially shifted onto the inner part 17 and/or over the retaining part 39
and/or
between radial protrusions, coding portions 63 or the like of the retaining
element 39. In the preferred embodiment, the holding portions 72 are
extending essentially in a circumferential direction and/or are relatively
rigid
and/or support one or more coding portions 63. Preferably, the key element 70
and/or holding portions 72 are provided with shoulders or noses 73, preferably
extending in circumferential direction and/or located at the circumferential
ends of the holding portions 72, in order to allow fixing or clipsing of the
key
element 70 or holding portions 72 to the nebulizer 1 or inner part 17 or
CA 02834318 2013-10-24
WO 2012/162305 PCT/US2012/038969

retaining element 39 and/or inbetween radial protrusions, holding portions 63
or the like of the nebulizer 1, inner part 17 and/or retaining part 39.
However,
other constructional solutions are possible.
The coding provided by the one or more coding elements 68, in particular by
protrusions and/or ribs 62 and/or indentions and/or grooves 71 of the coding
element(s) 68 or the like, is preferably coded by the peripheral location
and/or
extension and/or radial extension or dimension, inner contour or the like
and/or is preferably complementary to the coding provided at the nebulizer 1,
in particular provided by the retaining part 39, the key element 70 and/or the
coding portion(s) 63, in particular respective protrusions, recesses or the
like.
[0208] Only if the codings of the nebulizer 1 on one hand and the
housing part 18 on the hand match, the nebulizer 1 can be closed, in
particular
by shifting the housing part 18 on the inner part 17. If the codings do not
match, the respective housing part 18 and the associated container 3 cannot be
used with the respective nebulizer 1.
[0209] The possibility to code the nebulizer 1 and/or housing part 18
by
means of additional parts, such as the coding elements 68 and/or key element
70, in particular by attaching or clipsing respective parts to the nebulizer 1
and/or housing part 18, allows in particular a medicament or fluid specific
coding in an easy manner and/or allows a specific coding later after producing
multiple nebulizers 1 and/or housing parts 18, in particular independently
from
production and/or depending on demand.
[0210] As already mentioned, individual features, aspects and/or
principles of the embodiments described may also be combined with one
another as desired and may be used particularly in the nebulizer according to
Figs. 1 and 5 but also in similar or different nebulizers.

[0211] Unlike freestanding equipment or the like the proposed
nebulizer
1 is preferably designed to be portable and in particular is a mobile hand
operated device.
[0212] The proposed solution may, however, be used not only in the
nebulizers I specifically described here but also in other nebulizers or
inhalers,
e.g. powder inhalers or so-called metered dose inhalers.
[0213] Preferably, the fluid 2 is a liquid, as already mentioned,
especially an aqueous pharmaceutical formulation or an ethanolic
pharmaceutical formulation. However, it may also be some other
pharmaceutical formulation, a suspension or the like.
[0214] According to an alternative embodiment the fluid 2 may also
comprise particles or powder. In this case, instead of the expulsion nozzle
12,
some other kind of supply device may be provided, especially an expulsion
opening (not shown) or a supply channel (not shown) for supplying the fluid
to or powder or the like into the mouthpiece 13. The optional air supply
opening 15 then serves to supply ambient air preferably in parallel so as to
general or allow an airflow with a sufficient volume for breathing in or
inhaling through the mouthpiece 13.
[0215] If necessary the fluid 2 may also be atomized by means of a
propellant gas.
[0216] Preferred ingredients and/or formulations of the preferably
medicinal fluid 2 are listed in particular in WO 2009/115200 A1, preferably
pages 25 to 40, which is incorporated herewith by reference. In particular,
